Starting at $599, the Alienware X51 with Ubuntu knocks about $100 off the price of the same model loaded with Windows 7. The X51 functions as a slimmed-down version of a larger gaming rig, but higher configurations (starting at just over $1000) pack in nice components like a 3.4GHz Intel Core i7, 8GB of RAM, and an Nvidia GeForce GTX 660 graphics card.

Linux fans are probably delighted with the move, especially since Steam for Linux is fully available to the public. Valve has previously stated the upcoming Steam Box could run on the open-source platform. Be sure to check out IGN's review of the Alienware X51 for our take on the couch-ready gaming rig.
